1. Select the problem of the system
After thinking about each application, when the system is installed, you can be sure that all aspects of the application are what you need and avoid serious overspending caused by possible errors.
In addition to these, the working schedule of the robot is also one of the issues to be considered. When the travel is certain, it is not only based on the travel of the robot's technical parameters to determine whether it can reach the requirements of the application. It should wait until the end actuator is installed to determine whether the robot's motion path can reach the travel requirements. This is also one of the key reasons to stop the simulation.
For the environment, there will be customized industrial robots in different environments. For example, the spraying industry needs explosion-proof industrial robots, which is different from standard robots and the use of clean rooms. And the reliability of the robot, its defect rate, and the power consumption are all issues that must be considered when selecting.
2. Misunderstanding of accuracy and repeatability
An accurate machine can be repeated, but a repeatable machine does not necessarily have accuracy. Repeatability refers to the performance of the robot according to the regular working path, precisely reciprocating between the given positions.
Accuracy is expressed by accurately moving to a calculated point according to the working path. In the handling action, the robot moves to some fixed points through calculation, using the precise performance of the robot. Accuracy is directly related to mechanical tolerance and accuracy of robot arm.
Accuracy is closely related to the mechanical accuracy of the robot arm. The higher the accuracy, the higher the speed. The robot reducer is an important key structure to ensure the accuracy of the robot. Ordinary industrial robots use the RV type standard reducer.
3.Excessive reliance on the advantages and disadvantages of the control system
Most robot manufacturers think more about the controller of the robot than the mechanical performance. But suppose that once the robot is configured, the normal operation time mainly depends on the durability of the machine. It is likely that the loss of consumption ability of products is not caused by the poor controller and electronic equipment, but by the poor mechanical performance.
Usually, a robot system is selected based on the user's knowledge of the controller and software. Assuming that the robot also has excellent mechanical performance in this respect, it will be a very competitive advantage. On the contrary, if the robot needs to stop maintenance from time to time after installation, the time-saving advantage of control will soon be consumed.
The mechanical part is the key to ensure the performance of industrial robots. The accuracy, speed and durability are all closely related to the mechanical part. The structure of the robot is relatively simple. Generally, it is motor and reducer. It is very convenient to assume that the selected robot often needs to repair the reducer or other mechanical structures.
